ASX-listed Lucapa Diamond Company and the Government of the Kingdom of Lesotho are pleased to report the recovery of a 25 carat yellow gem diamond from the Mothae kimberlite mine in Lesotho.
Significantly, the gem-quality special was recovered from the Neck Zone of the Mothae
kimberlite, which is not part of the current +1 million carat JORC resource.
The diamond was recovered within the first two days of trial processing through the bulk sampling plant after recent efficiency and security modifications.
Following sign off of the modifications, Mothae will commence processing three 50,000 t bulk samples of kimberlite material from the Neck, North and South East Zones, with the aim of adding to the JORC resource and the mine life.
Other +5 carat diamond recoveries from the first two days of trial processing of material from the Neck Zone include a 6 carat diamond.
Meanwhile, construction of the new 150 tph treatment plant with XRT large diamond recovery technology continues on schedule for commercial production in H2, 2018.
Earlier this month the company recovered 46 carat pink.
It is the largest gem-quality coloured diamond recovered to date from Lucapa’s Lulo mining operations, eclipsing the 43 carat yellow gem recovered in January 2018 and the 39 carat pink recovered in September 2016.
Significantly, the 46 carat pink, along with other large special diamonds, was recovered from new Mining Block 4, which is an area planned for resource delineation in 2018 to be included in the alluvial JORC resource update. Mining Block 4 is located close to the treatment plant.
The frequent recovery of large and premium-value diamonds from new areas along the Cacuilo River valley continues to illustrate the uniqueness and potential of the Lulo diamond concession.
Lulo has already produced 10 +100 carat diamonds to date, including Angola’s two biggest recorded white Type IIa gems weighing 404 carats and 227 carats.
